PPT-1 Magnetic Properties of Materials

force in direction sample volume magnetic susceptibility magnetic field gradient of the magnetic field   The magnetic susceptibility characterizes the magnetic properties of materials. In addition magnetic fields create a force only on moving charges The direction the magnetic field produced by a moving charge is perpendicular to the direction of motion The direction of the force due to a magnetic field is perpendicular to the dir 1. .

Properties of materials are things that describe the appearance and characteristics of a material.. Examples of properties are:. Strong. Magnets attract objects made of magnetic materials. Magnetic materials include the elements . iron, nickel, cobalt, . alloys containing some of these such as . steel . and some of their compounds.. stainless steel.

Show students a piece of magnetite, and show them that a small magnet is attracted to it.

The purpose of this research is to observe and study the effects of temperature variations on the formation of and magnetic properties of Iron/Platinum (FePt) nanoparticles. We hope to find properties that will suggest that FePt particles can be used for magnetic recording in computer storage devices or as a replacement to currently used rare earth metals.. BY. D. PEGU.
